The implementation looks fine, especially given the test cases that back it up. I am only curious why the block size is set to a default of None. To put it as contcretely as possible: is there any expected configuration where None would work but 500 would not? We know there are many cases of the other way around, and those cases are going to send users to StackOverflow to find the right workaround.
Dropping the option would also simplify the code in several places. The complex logic around get_another_block could be removed, and instead there could be a loop from start to mostRecentCommit by block_size. Several places that check "if not block_size" could just choose the other branch.
